If someone gives me an idea and it’s about something I like to do, I tend to start right away. Not always nice for the people close to me, who actually hope that I will make some more time with the holidays for them. So this is going to be my last article of this year, and a kind of Christmas present at the same time 🙂
So, I started a new project to create an Acros film simulation including a RED filter.
I soon realized that applying a red filter on Acros does not have much effect, in fact Acros already has a reasonably high contrast image.
So I started my typical PictureFX extreme aproach, but with the typical Fujifilm Acros film curve and all its properties.
To my surprise I didn’t create an Acros+R, but kind of an Acros/Infra Red version – so I promptly gave it a name: PictureFX Fujifilm Acros 400 IR because I think Fuji should have one ! Why 400 ? well, this one is a bit more grainy than the Acros 100 II version. The Acros+R version will have to wait to next year.
As far as I know, Fuji has never made an Infra Red 35mm film, Fuji is active in the IR field, but rather through specially developed cameras. Fuji sensors also appear to be extra sensitive to IR light, but whether the results with this Lut have anything to do with this or whether pictures of Fuji cameras react more sensitively to this Lut is currently unknown.
This all happened fairly quickly, and I was not able to thoroughly test this film simulation with different test images containing variable exposure, lighting conditions and color variations.
So it may well be that under some circumstances the Lut reacts like a normal Acros but then on steroids. This Acros 400 IR version is a bit grainy – noise reduction is recommended
In RawTherapee I would apply a slight noise reduction as follows : use the key combination “alt d” or go to the tab “Detail” -> scroll down to “Noise Reduction” and activate -> then set “color space” to L * A * B * -> mode conservative -> Luminance – Slider – set to 25.
Ok, and now some pictures :
First one to show what I mean by Acros on Steroids, you will not see anything that indicates an infrared picture, but the picture is dark and has a high contrast :
In the next picture you do see typical IR properties :
